Method for manufacturing resistor end effect curves of thick-film integrated circuit

Abstract

The invention relates to a method for manufacturing resistor end effect curves of a thick-film integrated circuit, and the method comprises the following steps: a) printing 28 conduction bands B on a film-forming baseplate respectively, wherein spacing intervals A between every two adjacent conduction bands are 15mil, 20mil, 25 mil,..., 70mil, 75mil and 80mil, 14 kinds in total, respectively; b) printing a thick-film resistor r1-r14 with the resistor width of 40mil on the film-forming baseplate respectively; c) using a multimeter to measure the resistance of the thick-film resistor in the film-forming baseplate, recording the measured resistance in an Excel sheet, and getting N which is equal to R / Ri*(W / L) according to the formula that R=Ri*N*(L / W); and d) utilizing the drawing function of Excel to draw a resistor end effect curve map against the different resistor widths respectively. The invention has the following advantages: solving the resistor design error problem caused by the situation that a thick-film slurry manufacturer only provides a single conductor end resistor design curve, improving the design technical level of a thick-film circuit layout, ensuring the resistanceconsistency of the thick-film resistor during the practical processing and enabling the deviation among the resistances of the resistors with the same resistance to be less than 5% when lapping different conductor ends.
